Migratory-derived resources induce elongated food chains through middle-up food web effects ...
Abstract Background Seasonal movements of animals often result in the transfer of large amounts of energy and nutrients across ecosystem boundaries, which may have large consequences on local food webs through various pathways. While this is known for both terrestrial- and aquatic organisms, quantit...
